PLANT FAIR: The Royal Horticultural Society will be holding a plant fair at its most northerly garden – Harlow Carr in Harrogate – on May 5 from 10am to 4pm. Visitors will also be able to take advantage of the RHS advisory team, who will be at the garden for the whole weekend, May 4 and 5, to give expert advice on all areas of horticulture, as well as help with plant and disease identification.
